Using Indexed and Synchronous Events to Model and Validate Cyber-Physical Systems

open access: yes, 2015
Timed Transition Models (TTMs) are event-based descriptions for modelling, specifying, and verifying discrete real-time systems. An event can be spontaneous, fair, or timed with specified bounds.

Synchronous response modelling and control of an annular momentum control device [PDF]

open access: yes
Research on the synchronous response modelling and control of an advanced Annular Momentun Control Device (AMCD) used to control the attitude of a spacecraft is described. For the flexible rotor AMCD, two sources of synchronous vibrations were identified.

Grid Synchronization of Renewable Generation Systems Using Synchronous Power Controllers

open access: yes2017 IEEE 6th International Conference on Renewable Energy Research and Applications (ICRERA), 2017
The increasing penetration of renewable energy sources in power systems has increased the amount of generating units employing power electronics as their grid interface, instead of synchronous generators. Their different dynamics have brought new challenges for power system operators; in particular, the reduction of the total inertia of power systems ...

Simulation Study of Heavy Haul Train Longitudinal Force with Synchronous Control

open access: yes机车电传动, 2012
Longitudinal force has become an important index to evaluate synchronous control performance of heavy haul train. Mathematical model and simulation model based on Matlab/Simulink of train’s longitudinal dynamics was established.
